How rain gardens work
Conduct a soil evaluation
Calculate rain garden size
Use the following general guidelines to determine rain garden depth. If the slope is less than 4 percent (4 feet vertical in 100 feet horizontal), build the garden 3 to 5 inches deep. If the slope is between 5 percent and 7 percent, build a garden 6 to 7 inches deep. If you are working with a slope in the 8- to 12-percent range, make the garden about 8 inches deep. Remember, rain gardens are easier to install and tend to work best in places where the ground is relatively level.
